Abstract
Description
- The present invention relates to a display technology field, and more particularly to a display device.
- In the display technology field, a flat display device such as a Liquid Crystal Display (LCD) has gradually replaced the Cathode Ray Tube (CRT) display device. The LCD has many advantages of thin body, power saving, no radiation so that the LCD has been widely applied.
- The LCD display device in the current market is usually a back-light type liquid crystal display device, and including a liquid crystal display panel and a backlight module. Usually, the liquid crystal display panel is formed by a Color Filter (CF) substrate, a Thin Film Transistor (TFT) array substrate, a Liquid Crystal (LC) clamped between the color filter substrate and the TFT array substrate and a sealant. The operation principle is that placing liquid crystal molecules between two parallel glass substrates, at middle portion of the two glass substrates, many vertical and horizontal fine wires are existed, through applying a voltage to control the direction of the liquid crystal molecules such that the light emitted from the backlight module is refracted in order to generate a picture.
- Along with the development of display technology, more and more display devices having larger display area are required in the application. The conventional display device having a single display panel cannot meet this requirement, and a display device formed by multiple jointed display panels is formed. With reference to
FIG. 1 , which is a schematic structural diagram of a conventional display device formed by two display panels jointed together. The display device includes two liquidcrystal display panels 100 arranged at intervals, and a black matrix (BM)frame 200 disposed at outer sides of the two liquidcrystal display panels 100. When the display device is displaying, the two liquidcrystal display panels 100 can display, but theblack matrix 200 cannot be displayed, which causes a black line corresponding to theblack matrix 200 to be generated on the display screen of the display device. The display effect is affected, and the product quality is poor. - The Organic Light-Emitting Diode (OLED) display device is a new flat display device. The OLED display device has a broad application prospects because of self-emission, simple manufacturing process, low cost, low power consumption, high light-emitting brightness, wide operating temperature range, small size, fast response speed, easy implementation of color display and large-screen display, easy for implementing and matching with integrated circuit driver, easy for achieving a flexible display.
- A mini LED display device is a display device that integrates small size LED array on a substrate to function as a display pixel to realize an image display. Each pixel can be addressed, individually driving, and belong to a self-luminous display. The mini LED has a low power consumption and the color saturation is closed to the OLED so that companies regard the mini LED as a current research focus.
- The purpose of the present invention is to provide a display device that can eliminate the black line in the display screen of the jointed display panels, and has a higher product quality.
